Checking the integrity of a complete leak test circuit including the leak tester, the jig and all the interposing tubing and valves involves closing the isolation valve in the FCO210 and connecting the input port of the FCO210 to the calibration port on the front panel of the leak tester.

The test pressure for the particular leak test is adjusted within the leak test instrument. The isolation valve is opened, and the needle valve is adjusted to display the required leak rate in cc/m or cc/hr.

The FCO210 is then adjusted to begin checking the leak test circuit. A known leaker, or ideally non-leaking part is put into the test jig and a test cycle is started.

The resulting flow rate displayed by the FCO210 during the test phase is compared with the leak tester providing the basis for acceptance or rejection of the calibration of the leak test circuit.

Key features of the FCO10 Microcalibrator leak test calibrators:

Available in 0-20 cc/m, 200 cc/m, 2000 cc/m and 2000 cc/hr options

Maximum test pressure is 14Bar (1.4MPa)

Repeatability is 0.1%

Displayed value is temperature compensated

Each new FCO210 is supplied with a UKAS (equivalent to NATA) traceable certificate

Routine re-calibration to UKAS standards is also provided by Bestech Australia

Safe overload rating of the FCO210 microcalibrator is 20 x full range (cc/m)

Bestech Australia provides full technical advice and after sales support for the FCO210 Microcalibrator and FCO99 calibrated leaks, as well as the complete range of Furness instruments including leak detectors, ultra low pressure manometers and transmitters, and flow elements.
